Application filed June 15, 1912: Serial No. 703,850.

- To all whom it may concern.

Be it known that I, DANIEL A. Times, a citizen of the United States,residing in Stookey township, in the county of St.

Clair and State of Illinois, have. invented new and useful Improvementsin Corn- Planters, fication.

This inventiongrelates to corn planters, and it has for itsobject toprovide an at of which the following is a speci tachment or appliance ofsimple ,and inex pensive construction whereby co-rn may be planted incheck without the use of a check wire.

A further object of the invention is to provide a planter attachmentincluding a ground engaging wheel whereby the plantelevation of acrating wheel to the .55 d ary conventional corn planter, an B i ingmechanism is actuated and ,a special runner which is mounted in front ofsaid ground .engagingwheel to prepare a track for the same. With theseand other ends in view which will readily appear as the nature of theinvention is better understood, the same consists in the improvedconstruction and novel arrangement and combination of parts which willbe hereinafter fully described and particularly pointed out in theclaims. In the accompanying drawings has been illustrated a simple andpreferred form of the invention, it being, however, understood thatnolimitation is necessarily made to the preclse structural details thereinexhibited, but that. changes, alterations and modifications within thescope of the claims may be resorted to when desired.

In the drawings,-Figure l is a sectional corn planter constructed andequlpped in accordance with the invention; Fig. 2 is a top plan view ofthe same. Fig. 3 is a perspective detail view of the operating wheel andrelated parts, detached. Fig. 4 is a perspective detail view of thecross bar of the frame carrying the lever which is used in transmittingmotion from the op"- rock shaft, whereby the seed dropping mechanism isactuated. Fig. 5 is a perspective detail view, showing a portion of therock shaft with. the crank member applied thereto. Fig. 6 is aperspective detail view of the, auxiliary runner.

Corresponding parts in the several figures are denoted by likecharacters of reference.

A designates the main frame of an orthe axle having transporting andcovering Wheels C whereby the frame is supported.

D represents the runner frame which is equipped with. the runners 0rfurrow openers E, which are arranged directly in front of and inalinement with the covering wheels and with the seed boxes or hoppers F,the latter affording bearingsfor a rock shaft G, whereby the planting orseed dropping mechanism, which may be of any desired construct-ion, isactuated in the usual or 1n any customary or well known manner.

The rock shaft is normally actuated in one direction by means ofretracting springs H connected with arms I associated with the rockshaft. It is, well understood that -a rock shaft of this character isutilized in manyv types of corn planters for the purpose of actuatingthe seed dropping mechanism, and it is also well understood that by theextent to which the'shaft is rocked or oscillated, the valves governingthe escape of the seed may be actuated so as to regulate the number .ofseeds that are permitted to drop at each operation. These features arewell known in the art, and as they form no part of the presentinvention, it is not deemed necessary to further describe or toparticularly illustrate the same.

The improved attachment includes a pair Ofsupporting bars 1, the forwardends of which are connected with the side bars of the planter frame A,said supporting bars converging in a rearward direction and providingbearings for a shaft 2 carrying a ground engaging wheel 3, on the spokes4 of which is mounted a similar concentric wheel or rim 5. The wheel 3is supported] about midway between the covering and; transporting wheelsof which it is entlrely independent. The rear ends of the support- .ingbars 1 are connected by an upwardly extending yoke 6 which is positionedbeneath the drivers or operators seat 7 of the planter. Fulcrumed on oneof the limbs of the yoke 6 is a lever 8 which extends upwardly in thepath of pins or tappet members 9 which are associated with the wheel 5,adjacent to the rim of the latter, where said pins or tappet vmembersmay be secured in any convenient manner. The wheel 5 be -1ng smaller orof less diameter than the, ground engaging wheel 3 upon which it issecured, it follows that the tappet members 9 will supported clear pfthe ground so that clods of earth or clay will not adhere thereto andinterfere with the operationof the lever 11, or render such operationirregular. The cross-bar J of the planter frame which ispositioned abovethe axle B supports an angular bracket member 10 supporting a verticallydisposed lever 11, the upwardly extending arm of which is connected withthe lever 8 by a connecting rod 12.

13 designates a crank arm having at its u per end a hook 14 engagingtherock shaft upon which the crank arm is mounted and secured in anysuitable manner; for instance, by a set screw 15 engaging the rock shaftthrough the hook 14c. The crank arm 13 has a plurality of apertures 16one of which is connected by a link or connecting rod 17 with thedownwardly extending arm of the lever 11. The connections between thearms of the lever 11 and the rods 12 and 17, as well as the connectionsbetween said rods and the lever 8 and crank arm 13, are to be of such anature that the parts will be capable of operating freely andunobstru'ctedly.

Suitably connected with the runnei frame D which is provided with aforwardly ex-.

tending tongue K is an auxiliary ground engaging runner 18 which issituated directly in. front of the ground engaging wheel 3 so as toclear a track for the latter; the runner 18 is preferably connected withthe tongue by means of bars or connecting members 19. The runner 18 willserve to clear away any obstructions in advance of the ground engagingwheel 3 which travels in'the path thus prepared and the operation ofwhich will, therefore, .not be interferedvwith by clods, stones or otherobstructions lying on the ground. The ground engaging wheel 3 isprovided" with marking blocks 20 secured upon the rim of said wheel atdiametrically opposite sides for the" purpose ofmarking the ground inalinement with the places where seed is dropped, said marl'rers beingobviously secured in such a manner as to be,

readily adjustable to the proper position.

From the foregoing descrlption, taken in connection with the drawingshereto annexed, itwill be readily seen that the rock shaft whereby theseed dropping mechanism is actuated will be rocked or oscillated atregular intervals-by the action of the pins or tappet members 9associated with the wheel 5 which is concentric with and rotates inunison with the ground engaging wheel 3.v

or tappetmembers being located at diarmetrically opposite sides of therim of the wheel 5. The distance between the hillswill ,wheel has acircumference of eight feet, it

is. obvious that the seed dropping mechanism will be actuated atintervals of four feet, and so on, according to the circumference of thewheel. .The yoke 6 serves to guard the ground engaging wheel as well asthe tappet wheel 5, and also to support the lever 8 which is actuated bythe pinsor tapp'ets 9. The said yoke may also be utilized as a handlewhereby the ground engaging wheelcarrying the tappet wheel may be lifted.to a non-engaging position with respect to the ground. 1

Having thus described the invention, what isjclaimed as new, is

1. The combinatlon with a corn planter having a rock shaft associatedwith the seed dropping mechanism of said planter, and a retractingspring whereby said rock shaft is actuated in one direction, of a crankarm, means whereby said arm is mounted detachably on the rock shaft,rearwardly converging bars secured on the sides of the planter frame, anupwardly extending yoke connecting the rear .ends of said bars, a shaftsupported for rotation by said bars, a ground engaging wheel on saidshaft, a smaller wheel associated with the ground engaging wheel andconcentric therewith, tappet members connected with the rim of thesmaller wheel, a lever fulcrume'd on the. yoke and lying in the path ofthe tappet members, a

suitably supported intermediate lever, a rod connecting the upwardlyextending arm of said intermediate lever with the lever fulcrumed on theyoke, and a rod connecting the downwardly extending arm of the intermediate lever with the, crank arrn upon the rock shaft.

2. The combination with a corn planter having a rock shaft associatedwith the seed dropping mechanism and spring means whereby the said rockshaft is actuated in one direction, of a crank arm mounted on the rockshaft, a .ground engaging wheel mounted for rotation intermediate thesides of the planter frame, a/ smaller wheel associated with andconcentric with the groundengaging wheel, tappet members connected withthe smaller wheel, a lever supported in the path of the tappet membersand actuated thereby, and means for transmitting motion between saidlever and the crank arm on the rock shaft. p Y

3. In a device of the character described, aground engaging wheel, asmaller wheel connected with and concentric with the ground engagingwheel, tappet members associated with the smaller wheel, ground engagingmarking devices mounted on the r m of the ground engaging wheel, a leversupmitting motion from ported in the path of the tappet members andactuated thereby, and means for transsaid lever to the seed droppingmechanism of the planter.

4. In a device of the character described, the combination with aplanter frame having transporting and covering wheels and a runner frameassociated therewith, a ground engaging wheel supported intermediate theframe and about side members of the planter midway between thetransporting and covering Wheels, supporting means for said wheelincluding rearwardly converging bars con nected with the planter frameand a yoke connecting said bars and straddling .the wheel, a smallerwheel connected with and concentric with the ground engaging wheel,tappet members connected with the smaller wheel, a lever fulcrumed onthe yoke and retracted rock shaft, and an auxiliary runner associatedwith the runner frame and positioned directly in front of the ground en-,gaging wheel intermediate the sldes of the planter frame to clearthetrack for said wheel.
